Hammond Triplane
The Hammond Triplane was designed by E. V. Hammond and appeared at Brooklands in February, 1911. The pair of tractor propellers were belt-driven from the engine and the machine, which was tested by C. Howard Pixton, possessed a fore-elevator and ailerons of very broad chord on the upper wings.

HAMMOND triplane
The successor to the biplane appeared at Brooklands for engine testing at the beginning of January 1911. Its general construction was reported to be flimsy and the commentators of the time were doubtful of its potential. On the 14 January 1911 it was taxied at speeds up to 10 mph by Howard Pixton but, although further brief appearances were made, it was presumably abandoned soon after. Hammond claimed that it made several short flights with a 14hp engine but that it was underpowered.
The layout was similar to other types, usually biplanes, of the period but, unusually, it was a twin tractor with belt drive to the propellers, and the pilot behind the engine. Lateral control was achieved by means of unbalanced ailerons on the top plane. The machine was mounted on a four wheeled chassis, with skids under the wing tips to aid balance on the ground. No further details of the machine are recorded.

Mr. Hammond's "mono-bi-triplane" has at length also reached the engine-testing stage. This machine is certainly a marvel of light construction, so light indeed that it looks at first sight quite inadequate to support the weight of engine and aviator, to say nothing of landing in the ever popular sewage farm. We hope he will surprise the tenants, who appear in the meantime to be somewhat sceptical.
